Chrome extension for debugging and inspecting Google Tag Manager (GTM) dataLayer implementations directly from the browser without using the developer console

Developers and analysts need to frequently check dataLayer contents on websites to verify GTM/analytics implementations. This typically requires opening browser console and manually typing commands, which is tedious and error-prone. This extension provides a visual interface to view, search, and manage dataLayer data.

1. User visits any webpage with GTM dataLayer. 2. Clicks extension popup to see all dataLayer objects on the page. 3. Uses dropdown to switch between multiple dataLayers. 4. Views events in accordion format with table or JSON visualization. 5. Can search/filter events. 6. Takes snapshots to save dataLayer state locally. 7. Opens workspace to manage, filter, and batch-analyze saved snapshots. 8. Can reopen snapshot URLs to capture fresh data for comparison.

Target users: Web developers / Google Tag Manager implementers / Analytics engineers / Digital marketers verifying tracking implementations / QA testers checking analytics events

The deterministic heuristic produced multiple false positives: 'stripe' matched CSS variable --dt-row-stripe in DataTables; 'log in' matched '.toggle-log' variable name; 'pro' matched Promise/prototype/progress patterns. All were verified as non-payment/non-login through source inspection.
Umami analytics tracking is used (lib/umami/ scripts) to track extension usage, but this is analytics, not a required service.
The store description mentions 'EXCLUSIVE FEATURES' which could suggest paid features, but source code analysis shows no gating mechanism - all features appear available to all users.
